I believe that it is the first paper written in French on
buffer overflows. It is available on my webpage. That here.
The title is "Les débordements de tampons sur les systèmes
Unix".. that's "Buffer overflows on Unix systems".

Btw, I am releasing it under the following terms: "It can be
distributed without restrictions as long as its not
modified".
Mon essai peut être redistribué sans restrictions s'il n'est
pas modifié.
